Answer:
The answer is "Provide strong evidence for seafloor spreading".
Explanation:
The magnetic changes from east to west and vice versa are geomagnetic. geomagnetic reversals. And they can provide significant evidence of the expansion of sea bed in the rocks formed along the middle sea ridges by documenting the geomagnetic pattern of echo.
A new crust is developing from the magma explosion into the seafloor in the ocean along the mid-oceanic ridges along the mid-ocean ridges. When the magma cools, the minerals of ferromagnetism found in the magma will align as per the magnetosphere of this time.
In the event of geomagnetical revolutions, newly formed minerals will be reverse-aligned to early elements, thus registering the lithosphere on both sides of the mid-oceanic ridge. Lithosphere, one could argue, is a continual move away from oceanic crusts midway through.
Pretoria, Bloemfontein, Cape town
Riches from the land such as good and silver
The answer would be D.
As for The other options, it cannot be A because there is no way we could know if they are exactly similar. B states they are dramatically different when there is obviously some similarity. C states that they are from the same time period, which is impossible as there is no way a layer of sedimentary rock can be the same age as current day mud. There are likely many layers above the studied area that can denote the age.
